For sure, and FB notes amortized investments bringing this figure down. The tax code rewards corporations for R&D investments. I think it's working. The optics are terrible though.
I'm fairly confident FB would be making R&D investments regardless of the reward from the tax code. But for change in behavior due to the tax code, the tax credit is a windfall.
Additionally, that money is being taxed in the end via income tax at a comparable rate.
